PATENT @FFHCEO BENJAMN H. PURCELL, OF TERRE HAUTE, INDIANA, ASSIGNOR TO THE AUTOMATIC 'MACHINERY COMPANY, OF TERRE HAUTE, INDIANA, A CORPORATION, 0F INDIANA.

LEER FEEDER.

application filed February 9, 1920. Serial No. 357,488.

To @ZZ whom t may concern.'

Be it known that I, BENJAMIN H. PUR- CELL, av citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Leer Feeder, of which the following is a specification. My invention relates specifically to mechanism by which freshly formed glass articles may beautomatically delivered into a leer, but it will be understood that the mechanism which will be described may be utilized for other purposes.

In apparatus of the type to which my inventlon is applicable there is an endless carrier, upon which the articles are transported to a position in front of a transversely-operating pusher-bar, of such character that movement of the articles may be arrested while movement of the carrier may continue beneath them, stop mechanism' being provided to act in synchronism with the pusher-bar to arrest the articles' before arrival in front of the pusher-bar preliminary to and during movement of said pusher-bar, and the object of my invention is to provide an effective stop mechanism which will not crush or injure the articles and will notbecome choked so as to prevent operation of the machine.

The accompanying drawings illustra-te my invention. Fig. l is a plan of amachine embodying my invention, the receiving end of a leer being shown in horizontal section; Fig. 2 an elevation of the machine, adjacent portions of the leer being shown in vertical section; Fig. 3 a plan of my improved stopand an adjacent portion of an endless carrier on a larger scale; Fig. 4 a section on line 4 4 of Fig. 3; and F ig. 5 a section on line 5-5 of Fig. 3.

ln the drawings 10 indicates a main frame formed to be projected laterally through suitable openings 11 in the side Walls of the leer 12 at its receiving end. Mounted in frame 10. is an endless carrier 13 having an upper surface upon which articles 14 (dotted lines Fig. 3) mayy rest and be carried and capable of slipping beneath the articles when they are arrested. Carrier 13 isdriven by a suitable motor 15.l

Arranged alongside carrier 13 is a pusherbar 16 capable of traversing the carrier and shoving articles therefrom and onto a delivery platform 17 which leads to a carrier (not shown) in the leer. Bar 16 is supported by suitable guides 18 and is operated by suitable links 19, levers 20, bars 21 and 22, roller 23 and cam 24 driven by motor 15. A. fence 25 is placed across carrier 13 at the far end of bar 16 'to prevent articles 14 from being carried beyond the bar 16. Thus far the apparatus is of a common type.

In order to interrupt the How of articles to positions in front of the pusher-bar l provide a yielding gate of peculiar form. This gate comprises a main body 30 provided with sides 31 and mounted to reciprocate in a guideway 32 transversely of the carrier 13, reciprocation, in synchronism with bar 16, being obtained by means of link 33, lever 34, link 35, spring 36, bar 37 and roller 38 projected into cam 24 and advance of ro-ller 23.

Mounted so as to slide freely longitudinally'in body 30 are several stop-ngers 40, preferably, though not necessarily, of gradually decreasing length and bevelled forward4 ends. The weight of fingers 40 offers a required amount .of resistance to their movement in body 30 and this movement in one direction relative to body 30 is limited by pins 41 which engage a retainer 42 carried by body 30, and in the opposite direction of movement is limited by a bar anism just described is mounted at the rear,

or receiving, end of pusher-bar 16 and opposite, a fence 44 arranged alongside carrier 13.

The operation is' as follows Articles 14 are brought by carrier 13 topositions opposite the pusher-bar 16 and at regular intervals the pusher-bar is operated to shove the accumulated articles laterally from the carrier onto platform 17. J ust before pusher-bar starts, body 30 is moved toward carrier 13 so as to project ngers`40 across the carrier in front of oncoming articles. If, by chance, an article should be advanced to such a position relative to the first finger that said'finger could neither arrest nor pushv it back, it is apparent that further forward movement of this finger will be arrested by the article, Without injury to the article or the mechanism, .and that the body 30 Will contlnue 1n its projectfingers will be driven into position to arrest vthe article before any part of it can come into position in front of the pusherbar.

Upon return movement ot' body 3() any displaced fingers 4() .will be successively picked up by retainer 42 and returned t-o initial position, bar 43 insuring against any improper overthrow ot' fingers 4() on such return movement.

In case an article has progressed far enough in front of fingers 40 to reach a proper position in Jfront ot' the pusher-bar before it starts forward itis apparent that the bevelled ends of' fingers 4:() will tendto assist the article to reach this favorable position and thus prevent any possibility of crushing the articleI between felice 44 and the pusher-bar.

I claim as my invention:

l. Thefcombination with an endless carrier, of astop mechanism comprising a main body movable transversely of the carrier. a plurality of stop-fingers having bevelled active ends associated with said body at successive positions lengthwise of the carrier and'independently yieldingly movable by said body transversely of the carrier.

2. The combination with an endless carrier, ot' a. stop mechanism comprising a main body movable transversely of the carrier, a

plurality of stop-fingers associated with I said body at successlve posltmns lengthw1se of the carrier and independently yieldingly movable by said body transversely of the carrier.

3. The combina-tion with an endless carlongitudinally.

rier, of a stop mechanism comprising a main body movable transversely of the carrier, a plurality of stop-fingers having bevelled active ends frictionally carried by said main body at successive positions lengthwise of the carrier and yieldable on the main body longitudinally, and one-way engaging means carried by said fingers and main body.

4. The combination with an endless carrier, of a stop mechanism comprising a main body movable transversely of the carrier, a plurality ot' stop-fingers frictionally carried by said main body at successive positions lengthwise of. the carrier and yieldable on the main body longitudinally, and one-way engaging means carried by said fingers and main body.

The combination with an endless car rier, of a stop mechanism comprisinga main body movable transversely ot the carrier, a plurality of stop-fingers having bevelled active ends frietionally carried by said main body at successive positions lengthwise of the carrier and yieldable on the main body The combination with an endless carrier, ot' a stop mechanism comprising a main body movable transversely of the carrier, a plurality of stop-lingers'frictionally Carried by said main body at suceessiverpositions lengthwise ot the carrier and yieldable on the main body longitudinally.

In witness whereof, I have hereunto set my hand at Terre Haute, Indiana, this 24th dav oi' January, A. D.. one thousand nine hundred and twenty.v
